PM / Domains: Rename the always_on device flag to syscore
The always_on device flag is used to mark the devices (belonging to a PM domain) that should never be turned off, except for the system core (syscore) suspend/hibernation and resume stages. Change name of that flag to "syscore" to better reflect its purpose. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
